ww whisper tip vs. sench q

Post by titan » Sat Jan 08, 2011 12:41 pm

which prop would have more push on a 12 ft boat with a mild built 350 and a 2:1 gear box?
Or do they have the same performance?

The Q series is only built in left hand rotation, for a 2 to 1 gear reduction you want to look at the R series.

I have a 78" R series on my 13'6" Glass boat with poly that is not especially light. It has a very mild smallblock/2:1 box combo and performs pretty good,it will run the dry with three people and go dang near anywhere with two on it.

There are 500+ people on this board who love their Sensenich Q....to say it "sucks" is nonsense...

ouch !!! I will say they push equally at different places in the rpm range ... when adjusted correctly for the application on which they are used. I can't agree that either one of them is junk. I sell both and it depends on what the customer preference is and the application ... but the customer should get what they want .. maybe with a cautionary statement but get what they ask for.

casino i'm going to bring a ngh when we thrust test so i can make you spend more $ :D
ps saw your rigging today it was getting buffed and polished..

i have run the q and sold a pile of them. its a great prop and has been on top for years. there are some rank boats with q's and some strong hunt boats as well that will root. Sensenich has moved forward with a couple of blades that are great. the saber is starting to take off as people learn how to set them up. I am most impressed with the ngh. it has out performed in one way or a another every prop it has gone up against. the q is tried and true and was closely imitated for a reason. if i was in the market for a strait drive ride boat prop i would aim at the ngh. i will bring one by and bolt it on to any one that is interested. thanks dan

So Dan what is the ngh.
You know we are always looking for better performance.

I have used both the q and the whisper. My bud has a Q right now but literally it hurts my ears so bad I cant ride in it. yes that with ear plugs and muffs on. Has anyone else complained about the Q harmonics at the top end.

I should clarify my last comment ... I probably only get ride of that Q for a 3 blade NGH. Never run a WW-WT so I can't compare. I have NO complaints with Sensenitch.

let me clarify the sucks part. In comparison i can rid in a boat with a whisper tip at wot but not a Q. for my experience i can not use the propeller it useless or otherwise junk to me. Maybe it was just a bad q but its the only prop i have ever felt that type of pain from. It more like a harmonics not really a sound. I know im not the only one to feel it others have said the same.

I have a "Q" and my wife rides with no ear muffs, very quiet! my buddy has a whisper tip on a DD caddy and when he pulls up next us it will damn near make your ears bleed. I will say this, i did not notice this until James said something but it seems that the "Q" does seem to die on the top end but has nasty push on the bottom where it counts.

Just the opposite for me. The only time i notice the problem with the Q was above 2600. It seam to create a pitch that you really did not hear but would actually make your ear hurt almost intensely. Most said they felt it in the back seat only. Like a wave or frequency coming of the prop. I really like to know what it was.

ted, I would say you had your Q PITCHED way wrong.......
Did you try it around 2850????

If you did I would check your tach, I have seen tachs off as much as 300 rpms.

Buddy thought he was pushing 2850 but was really pushing 3150............

NOW THAT WILL HURT YOUR EARS -on ANY PROP!!!!!!!

Dont have the q went to the whisper and set the rpms at 2900.
Still looking for more push that ether of those will provide. This boat sucks fuel. Make me wonder about a gear box for the 540.
Yes i know even more fuel. So i am curious what this ngh is or does.

You either have one HEAVY ass barge,or your fuel system needs work.I have an injected 540 on a 13' Alumitech and I can ride all day at Kissimmee on 20-25 gallons.Last time i was there we rode 113 miles and I burnt 32 gallons.

at the severe risk of getting beat to death LOL I will make this statement once again .. both of those props are totally capable of delivering every bit of thrust your engine will develop. What do I mean by that .. it is simple ... thrust comes from engine power period .. all a prop does is convert the rotational power of the engine into thrust .. both the whisper tip and the Q are more than capable of doing that. If you want more thrust you are gonna need more engine unless your setup is off in some way and I am fairly certain you would have checked that stuff by this point. There is no magic bullet hiding in a prop .. it is all about engine power as long as the proper prop is being used .. in other words you cant expect a four blade warp to hold back the same engine that needs a four blade S to hold it down.

A gearbox will allow you to turn a bigger prop either in pitch/twist or diameter slower and still generate the same amount of thrust, the same within a few pounds. Gearboxes are only a transmission they do not increase power. POWER is THRUST ... THRUST is POWER. Sometimes power is expressed as TQ and sometimes it is expressed as HP. Slow turning a/c engines while commonly expressed as hp are actually better expressed as tq. a V8 engine is usually expressed as hp because they turn more rpms. A gear box allows them to get to their power band which is outside the operating range of most props.

I will say the Q not having top end is crazy. The 2 fastest boats I have been on had Q's. Maybe those with "no top end" need to check into their hull/rigging combo. One is a Davis 3/4 deck and the other is an Al David full deck, both with angle valve 540s.
